Sonar service outage

In order to provide a more reliable database backend for our Sonar services, we migrated the Sonar database to a new database server. However the data-migration failed for some Sonar instances.

Sonar instances impacted by this issue would be unable to connect to the database and thus unavailable during the outage.

To maintain the integrity of affected Sonar instances we have successfully re-migrated the impacted databases.

Upon restart of Sonar, some Sonar instances were in an inconsistent state having had plugin updates via the UI which were incompatible with the version of Sonar currently deployed at CloudBees.  Our engineers have completed correctly upgrading impacted Sonar instances.

The Sonar service is now back online.
